Application filed October 28, 1910. Serial No. 589,643.

To all whom it may concern Be it known that I, NELS P. Fmmn, a citizen of the United States, residing at Marquette, in the county of Marquette and State of Michigan, have invented cert-am new and useful Improvements in Ore Loaders, of which the following is a specification.

This invention relates to a loading apparatus, whereby ore or other material can be loaded from a pile on the ground to a car on which the apparatus can be mounted, or which may be brought up to the apparatus in carloading relation thereto.

The invention has for one of its objects to improve and simplify the construction and operation of car loading machines so as to be' reliable and efficient in use, readily controlled, and capable of transferring material from the pile to the car with great rapidity and requiring a minimum number of operators to operate the machine.

Another object of the invention is the provision of an inclined way or plane which has its lower or receiving end disposed at the pile of ore or other material to be loaded,

and its upper end in overhanging relation to.

the car body, and in connection with" this way or plane, a shovel or scoop is drawn up the same by an engine-driven drum and cable to the top of the plane where the shovel passes upon an automatically tilted cradle or dumping. device, the shovel being carried back to the pile manually for receiving another load.

Another object ofthe invention is the emloyment of means for automaticallyo ening the clutch that connects the cable winding drum with the engine when the shovel or scoop has reached dumping position at the upper end of the plane or inclined way.

With these objects in view and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts'which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawing, which illusgtrates one-embodiment of the invention, Figure 1 is a plan view of the machine showing the scoop or shovel in dumping position by full lines and in load-receiving position by dotted lines. Fig. 2 is a side View thereof.

Fig.3 is a detail sectional view showing the device for clamping the machine to the track rail in fixed relation to the pile of dirt to be loaded on the car. Fig. at is a detail view of the clutch for the cable Winding drum.

Similar reference characters are employed to designate corresponding parts throughout theviews.

In the present instance, I have illustrated a loading machine as combined with the car body to be loaded, both the body and machine being mounted on a common trucksupported platform or frame. It is to be understood, however,- that the machine can be mounted on its own base and the car to be loaded, such as an ordinary coal or dirt car, can be brought up to the same in loading relation thereto.

Referring to the drawing, A designates a car base 'or platform supported on wheelsl that travel along the railroad track 2 that leads up to the pile B of ore or other material to be hauled away. On the platform A is mounted a loadreceiving body C and the loading apparatus or machine D. The car is moved along the track into proper relation with the pile B, and after the load has been placed in the body C, the car is moved away to the point where the material is to be dumped or used. In loading the car body, the car is clamped to the track so'that it cannot move with respect to the pile, and for this purpose, the platform A has a depending clamping device 3 fastened to the side ,or receiving end 0 the way can be placed in proper relation to the pile B. The bottom of the plane or way may be made of sheet metal or the like and is flat or smooth, and at the edges are upstanding flanges 8 to prevent the shovel or scoop E from slipping laterally off the way, and also for forming rails on which rollers 9 on the sides of the scoop or shovel travel so as to minimize the friction between the scoop and way. The receiving or lower section 7 has its lower end flared so that the scoop can more readily enter the same. The main section of the way terminates close to the inner end of thef car body C, but, the side beams or rails 8 continue considerably beyond this point in overhanging relation to the body C, so that the scoop or shovel can pass to a pointapproximately atthe centertof the body. The upper ends of the rails on the inclined way are held rigid by braces 10 that are secured to the platform A. Inother words, the inclined way or track overhangs the body C, but the bottom of the way terminates shortof the same. v

Arranged over the body C is a tilting,

dumping device or cradle F which is in the form of a plate or platform 11 that is nor: mally dis osed in the same plane with the bottom 0 the main section 5, and the ends of this cradle are formed with segmental gears 12 that mesh with rollers 13 that are so disposed as to form racks parallel with the inclined plane or way but below the same. These rollers are'attachments of vertical plates 14 which are pendent from the sides 8 of the way, and the cradle F is adapted to tilt on the rollers when the load is to be dumped from the shovel to the car body C. On the sides of the cradle are upwardlyextending lugs 15 that are normally disposed ,Ib'e noted that when the cradle and shovel f conducted up the inclined way by in the path of the rollers or wheels 9 on the sides of the shovel so that as the shovel ascends, the rollers-will strike the stops and cause the cradle to tilt to the position shown in Fig. 2, and as a consequence, dump the material from the shovel that is, for the time being, carried by the cradle. It will are in tilting position, the center of gravit I is so disposed that the cradle will drop bac to normal position so that the shovel can be inoved down the inclined way or planefito receive another load.

The shovel or scoop E is adaptedto be an engine 16 which is located on the car p at-form un. der the main section of the inclined way, and this engine drives a windin drum l7 on a shaft 18 that is connected by a gear a bail 27 fastened to the sides of the scoop or shovel. The shovel is provided with a handle bar 28 at its rear end whereby an operator can 1111 the shovel back to the pile, or, if'desire a rope can be attached to the bar 28 so that the operator can remain on the pile and draw the shovel back to loading position, the said rope being, of course, paid out as the shovel with its load is drawn up:

ally or automatically. A rod 46 may the inclined way the engined will: be j noted that the pomtof connection- -29 between the bail 27 and shovel is' so located the pile on tothe inclined way.

shovel to take up its full load and pass from i The winding drum is adapted'tobe automatieallydisconnected from the engine after the shovel is'Itransfe'rred from the bottom of the'inclined way to t-he'cradle and the cradle hasmoved to its tiltedposition. This is effected by means of a trip 30 located at the upper end of the inclined way. in such position'as to be engaged by a'stop '31 on the cable, the said trip being operatively connected with the lever 32 of the clutch 33.

The trip 30 is mounted on the rock shaft 34 thathas a crank arm 35 whichis connected by a rod 36 with the'crank arm or lever 37 fastened to-a shaft 38 supported on the side of-the inclined way. fOn this, shaft 38 is a 41- that is fulcrumed at 42 on a. suitable part of the frame-of the machine, and this lever has an arm 43 connected'by a rod 44 with/- the lever 37. The controlling lever may be provided with a counter-balanceweight 45 so as to hold the clutch open when it has been moved to such position either manulead from the clutch lever to the throttle valve the same time the clutch is open, the throttle valve and clutch being both under the cont-rol of the operating lever 41 or the trip 30.

After the clutch has been thrown open by the shovel having reached itsdumping os1- I tion, the clutch will remain open unti the operator has drawn the shovel back to the p1le,. and when a signal is given, the engineer will close the clutch and open the throttleby manipulatin the lever 41. In doing this, the shovel W111 be drawn downwardly into the pile to receive its load of material and it will then pass upon and move up the inclined way to be automatically dumped when it passes upon the cradle.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the prmciple of operation of the invention, together with the apparatus which I now consider to be the best embodiment thereof, I desire to have it understood that the apparatus shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.

Having thus described the invention, what I claim as new, is

1. The combination of an inclined way, a

scoop movable along the same, a tilting cradle upon which the scoop passes from the upper end of the we a cable connected with the scoop, a win ing device connected I with the cable, an engine, a clutch between the engine and windmg device, means for automatically opening the clutch after the scoop reaches the cradle and tilts therewith,

and a throttle valve controlling means automatically operated with the clutch.
